Donepezil or EGb761 in Improving Neurocognitive Function in Patients Who Have Previously Undergone Radiation Therapy for Primary Brain Tumor or Brain Metastases

2014-08-26 22:54:53 | BioPortfolio

Summary

RATIONALE: Donepezil and EGb761 may be effective in improving neurocognitive function (such as thinking, attention, concentration, and memory) and may improve quality of life in patients who have undergone radiation therapy to the brain.

PURPOSE: This phase II trial is studying how well donepezil or EGb761 works in improving neurocognitive function in patients who have undergone radiation therapy for primary brain tumor or brain metastases.

Description

OBJECTIVES:

Primary

- Determine the effect of donepezil or EGb761 on neurocognitive function in patients who underwent radiotherapy for a primary brain tumor or brain metastases at least 6 months before study registration.

Secondary

- Determine the toxicity of these drugs in these patients.

- Determine the quality of life of patients treated with these drugs.

- Quantify the extent of radiation-induced white matter disease and temporal lobe atrophy in patients treated with these drugs.

OUTLINE: This is an open-label, multicenter study.

- Group 1 (closed to accrual 10/09/03): Patients receive oral donepezil once daily for 24 weeks.

- Group 2: Patients receive oral EGb761 three times daily for 24 weeks. In both groups (group 1 closed to accrual 10/09/03), treatment continues in the absence of unacceptable toxicity.

In both groups (group 1 closed to accrual 10/09/03), quality of life and neurocognitive assessment is performed at baseline and at weeks 6 (group 1 only), 12, 24, and 30.

Patients are followed at 6 weeks.

PROJECTED ACCRUAL: A total of 70 patients (35 per treatment group) will be accrued for this study within 9.5 months. (Group 1 closed to accrual 10/09/03)

Medical and Biotech [MESH] Definitions

Nervous system infections caused by tick-borne spirochetes of the BORRELIA BURGDORFERI GROUP. The disease may affect elements of the central or peripheral nervous system in isolation or in combination. Common clinical manifestations include a lymphocytic meningitis, cranial neuropathy (most often a facial neuropathy), POLYRADICULOPATHY, and a mild loss of memory and other cognitive functions. Less often more extensive inflammation involving the central nervous system (encephalomyelitis) may occur. In the peripheral nervous system, B. burgdorferi infection is associated with mononeuritis multiplex and polyradiculoneuritis. (From J Neurol Sci 1998 Jan 8;153(2):182-91)

The part of CENTRAL NERVOUS SYSTEM that is contained within the skull (CRANIUM). Arising from the NEURAL TUBE, the embryonic brain is comprised of three major parts including PROSENCEPHALON (the forebrain); MESENCEPHALON (the midbrain); and RHOMBENCEPHALON (the hindbrain). The developed brain consists of CEREBRUM; CEREBELLUM; and other structures in the BRAIN STEM.

A term used in Eastern European research literature on brain and behavior physiology for cortical functions. It refers to the highest level of integrative function of the brain, centered in the CEREBRAL CORTEX, regulating language, thought, and behavior via sensory, motor, and cognitive processes.

Pathologic conditions affecting the BRAIN, which is composed of the intracranial components of the CENTRAL NERVOUS SYSTEM. This includes (but is not limited to) the CEREBRAL CORTEX; intracranial white matter; BASAL GANGLIA; THALAMUS; HYPOTHALAMUS; BRAIN STEM; and CEREBELLUM.

A vascular anomaly characterized by a radial or wedge-shaped arrangement of dilated VEINS draining into a larger vein in the brain, spinal cord, or the meninges. Veins in a venous angioma are surrounded by normal nervous tissue, unlike a CENTRAL NERVOUS SYSTEM CAVERNOUS HEMANGIOMA that lacks intervening nervous tissue. Drainage of venous angioma is fully integrated with the body's venous system, therefore, in most cases there is no clinical signs and rare bleeding.
